Java doesn't allow multilevel inheritance instead it has interfaces and abstract classes. Explains what multilevel inheritance is and the difference between an interface and an abstract class
Write a Java program with the following: An abstract superclass with one abstract method that sorts an ArrayList object in ascending order. A subclass that overrides the abstract method in the superclass. A class ACTIVITY that contains main(). in main(): Initialized an array of strings with at least ten(10) elements and use this array as the elements of the ArrayList object. Create an object of the subclass and use this object to sort the ArrayList object. Display the sorted list.
Consider the relationship between Unordered and Ordered lists. Is it possible that inheritance could be used to build a more efficient implementation? Implement this inheritance hierarchy. Provide the screenshot of your inheritance hierarchy in your paper. Your paper should be 1-2 pages in length (not including title and references pages)

Computer Science There are clearly some similarities in the implementations of Taxi and Shuttle that suggest use of inheritance to represent them. Introducing inheritance is the primary task of this assessment. -The Ezcab class, The Ezcab class maintains separate lists of taxis and shuttles and destinations with destination fares (you can hardcode destination fares). It has a lookup method that searches for a taxi/shuttle with a given ID. -The Taxi and Shuttle classes share some common attributes – location and destination. They also have some common methods – getLocation, getDestination, getStatus and setDestination. -Vehicle is the superclass of both Taxi and Shuttle. This class involves placing the common fields and methods into Vehicle and removing them from Taxi and Shuttle. -Modify Taxi and Shuttle class to indicate that it is a subclass of Vehicle. You can keep the id field in Vehicle class and getId,SetId methods. -Arrange for Taxi's constructor to call the constructor of…
